The purpose of this study is to determine whether BA058 (abaloparatide), a parathyroid hormone-related peptide, is effective in preventing fractures in postmenopausal women with severe osteoporosis who are at risk of fractures.

A Randomized, Double-blind, Placebo-Controlled, Comparative Multicenter Phase 3 Study to Evaluate the Safety and Efficacy of BA058 (Abaloparatide) for Injection for Prevention of Fracture in Ambulatory Postmenopausal Women With Severe Osteoporosis and at Risk of Fracture

This is a randomized, double-blind, placebo-controlled, comparative Phase 3, multicenter international study to evaluate the efficacy and safety of BA058 (abaloparatide) 80 µg in the prevention of fracture in otherwise healthy ambulatory postmenopausal women with severe osteoporosis.

Eligibility

Ages Eligible for Study:

50 Years to 85 Years

Genders Eligible for Study:

Female

Accepts Healthy Volunteers:

No

Criteria

Inclusion Criteria:

Healthy ambulatory postmenopausal (≥ 5 years) women from 50 to 85 years of age (inclusive) with a diagnosis of osteoporosis

The women are to have a bone mineral density (BMD) T score ≤ -2.5 and > -5.0 at the lumbar spine or hip (femoral neck) by dual energy x-ray absorptiometry (DXA) and radiological evidence of 2 or more mild or one or more moderate lumbar or thoracic vertebral fractures, or history of low trauma forearm, humerus, sacral, pelvic, hip, femoral, or tibial fracture within the past 5 years. Postmenopausal women older than 65 who meet the above fracture criteria but have a T score ≤ -2.0 and > -5.0 may be enrolled. Women older than 65 who do not meet the fracture criteria may also be enrolled if their T score is ≤ -3.0 and > -5.0

History of more than 4 mild or moderate spine fractures or any severe fracture

Abnormality of the spine or hip that would prohibit assessment of bone mineral density (BMD)

Unexplained elevation of serum alkaline phosphatase, history of bone disorders (such as Paget's disease) or a diagnosis of cancer within the last 5 years (with the exception of basal cell or squamous cancer of the skin)

History of thyroid, parathyroid, or adrenal disorders, or malabsorptive syndromes or any chronic or recurrent diseases or disturbances that would interfere with the interpretation of study data or compromise the safety of the patient

Prior treatment with bisphosphonates, fluoride, or strontium within the past five years or treatment with androgens, anabolic steroids, corticosteroids or selective estrogen receptor modulators within the past 12 months (except hormone replacement therapy)

Prior treatment with an investigational drug within the past 12 months

History of nephrolithiasis or urolithiasis within the past five years, or history of osteosarcoma at any time
